PROPAGANDA APPARATUS APPLICABLE TO ELEGTRICAT; FANS OR MOTORS.

Application filed November 9, 1922, Serial No. 599,946.- RenewedFebruary 18, 19 25.

' To all whom it may concern:

Be it known that I, EMILIO RODRIGUEZ E'roHE'ro, a citizen of theArgentine Republic, and a resident of Buenos Aires, Argentine Republic,have invented a new and improved Propaganda Apparatus Applicable toElectrical Fans or Motors, of which the tfollowing is a full, clear, andexact descripion.

My invention refers to a propaganda apparatus which can be affixed toany class of electric fan. For the sake of greater clearness theinvention is illustrated in various figures, viz;

Figure 1 is a view in front elevation of an apparatus without disks, butshowing the drum or cover to demonstrate the distribu-' tion of theelectric bulbs,

device when aflixed to a fan, and

Fi ure 7 is a detail sectional view drawn to a arger scale and showingparts carried by the auxiliary axle,

Figure 8 is a view in side elevation of a double apparatus. I

The apparatus invented by me consists of a number of transparent disks,one withv painted letters constituting the text of the advertisement,another painted in various colors in sectors, a disk of opaque glass, atwo-winged obturator disk, some electric bulbs, and a drum or coverenclosing all the disks, the whole apparatus afiixed to a common fanmotor.

First of all the blades (11) are taken off the fan (1), and onto theaxle of the motor an auxiliary axle (10) is placed serving as aprolongation of the former shaft (see Figs. 2, 6 and 7). This auxiliaryaxle (10) is affixed to the axle of the motor by means of a screw (12).The drum (2) is then aflixed by'means of "the screws (3) with which thelid of the casing of the motor is fastened onto the motor. Preferablyfour electric bulbs (4) are affixed within the or some other suitablematerial is affixed,

the object of this disk being to difi'use the light derived from thebulbs (4). In the centre of the disk (5) is formed a hole of aconvenient diameter on the edge of which a grooved ring (13) is appliedto serve as supporting seat for a half or entire transparent disk (6) onwhich the text of the advertisement is written. This disk (6) isexchangeable and is introduced into the apparatus through an opening(22) formed in the circumference of the drum Onto the auxiliary axle(10) is now applied a disk (7 This disk is loose so as to revolve on theaxle (10) and, like the others, transparent, and is made from celluloidor some other material and conveniently painted in various sectors or iniris fashion with different colours. This disk is provided with a metalbush (14) and with two or more openings, windows or transparencies (20and 21) on its surface, serving the object of making it possible to readthe let-' tering, and which for this reason must beof the same radius asthe letters of the disk (6)., The obturator disk (8) consisting of twogreat blades or wings is now put on; these blades, which must be black,can be made from tin plate, brass or some other convenient material. Theobturator, which may be of various shapes, may in parts consist oftransparent coloured material so as to obtain a larger number of shadesof colour. The obturator (8) is provided with a bush (17) afl'ixed to itby means of screws. This bush (17) has a pressure screw (18) forfastening it onto the auxiliary axle (10). Between the disk (7) and theobturator (8) a ring (16) is afiixed, same being made'from gutta-percha,rubber, ebonlte or some other adequate material so as to producefriction against the disk (7) and thus imparting variable revolutions tosame according to the degree of its rubbing against the ring (16) whichmay be tightened at will by means of the bush (17) of the obturator 8)Finally a disk of clear glass (9) is now put onto the frame or edge ofthe drum (2) allowing the axle to revolve freely since the disk (9) isprovided with a sufficiently large hole in the centre. y

Once all this has been done the blades of the fan are affixed at theextremity of the auxiliary axle. 1

In the drum (2), conveniently distributed, some ventilation holes "havebeen provided.

As shown in Fig. 8 a double apparatus can also be constructed using thetwo extremities of the motor axle. n

In cold weather or in the winter the fan can also be used as apropaganda apparatus by simply taking the blades off.

The working is very simple since when the fan is started, same and theobturator revolve with the identical high number of revolutions, and, inconsequence, the obturator by means of the ring (16), which, as alreadystated above, is made from rubber,

gutta-percha or some other material, and the axle itself, also imparthigh revolutions to the transparent disk painted in various colours, butthese revolutions instead of being constant are alternating according tothe .time of friction with the ring, and 1n conformity with thesealternating revolutions the inscriptions of the disk (6) appear. Thebulbs aflixed behind all the disks light up the whole so that when thecolour disk performs its alternating revolutions 1n combination with thehigh and constant revolutions of the obturator, the effect ofvaricoloured rings changing every moment is produced, and in these ringsthe inscriptions appear periodically, the whole producing an aestheticeffect which also catches the eye.

Having thus described my invention and the manner of putting it intopractice, I declare that what I claim as my invention and exclusiveproperty is:

1. A device of the character described, comprising a stationarytranslucent member, a source of light at the rear of said member, astationary transparent member forward of the first member and havingcharacters thereon, a rotatable member forward of the last named memberand having slots through which said characters may be observed and alsohaving colored sections, and a rotatable obturator forward of the saidrotatable member.

2. In combination with an electric motor of the character described, acylinder hous ing, means whereby the housing may be secured to the motorand extend axially with the drive shaft of said motor, means forsupporting electric lights within the housing upon the inner endthereof, a stationary translucent member carried by the housing andpositioned forward of said lights, a member of transparent materialcarried by the housing and positioned on the forward side "of thetranslucent member and having characters thereon, a member mounted onthe shaft of said motor to have variable rotary movement and positionedforward of the character member, the said member being transparent andhaving slots through which the characters upon the said member may beobserved, and an obturator mounted on the said shaft forward ofsaidmember.-

3. In combination withan electric motor of the character described, acylinder housing, means whereby the housing may be secured to the motorand extend axially with the drive shaft of said motor, means forsup-porting electric lights within the housing upon the inner endthereof, a translucent member carried by the housing and positionedforward of said lights, a stationary member of transparent materialcarried by the housing and positioned on the forward side of the saidtranslucent member and having characters thereon, a disc loosely mountedon the shaft of said motor and positioned forward of the charactermember, the disc being transparent and having slots through which thecharacters upon the said member may be observed and also having sectionsof different colors, and an obturator fixedly secured to the shaftforward of the said disc, and means for imparting variable rotarymovement to the said disc.
